    • PURPOSE: A sealing apparatus is provided to reduce frictional force between a rotating body and a fixed body so as to extend the life span of the sealing apparatus and provided optimized sealing performance. CONSTITUTION: A sealing apparatus comprises a ring-shaped body and a side recess(44). The ring-shaped body is installed in a mounting recess. The mounting recess is formed in the circumferential direction in a rotating body(30) rotatably supported to a fixed body. The outer face of the ring-shaped body comes into contact with the fixed body. The side recess is formed one of the other side of the body and the other side of the mounting recess. The external air of the rotating body flows through the side recess into the gap between the other side of the body and the other side of the mounting recess. The external air flows through a gap between one side of the mounting recess and one side of the body and a gap between the outer face of the mounting recess and the inner face of the body.

    • PURPOSE: An apparatus for compensating thermal deformation of a strut in a gas turbine is provided to prevent damage of a strut and a case due to thermal deformation by keeping a gap between the case and the strut. CONSTITUTION: An apparatus for compensating thermal deformation of a strut in a gas turbine comprises a strut(60), a case(40), and a strut fixing unit(70). The outer end of the strut is separated from the case in order to dynamically absorb the thermal transformation difference between the case and the strut. The strut fixing unit controlling the interval between the case and the strut includes a housing(71) with a coupling hole to expose the top of the strut and a through hole(712) corresponding to the coupling hole, a supporting bolt(72) with the bottom inserted into the through hole and connected to the strut and with the top arranged inside the housing, and an elastic support member(73) which is coupled with the supporting bolt to elastically support the up and down movement of the supporting bolt.
